Since the 4 sectors of the spinner are equal, the probability of spinning any one of them is 1/4. Coins are always 50/50, so the probability of tossing a head with a penny is 1/2. Since the question is spinning C AND tossing a head with a penny, you must multiply the two previously found probabilities. 1/4 times 1/2=1/8 so 1/8 is the answer.
